KST3906TF Offers Compact, Reliable PNP Switching

The KST3906TF is a Samsung PNP bipolar transistor built for general-purpose switching and amplification. Its 40 V collector-emitter rating and 200 mA collector current make it suitable for low-power control stages, signal circuits, and compact electronic assemblies. The SOT-23 package also supports space-conscious PCB layouts and surface-mount production.

Designed for three-terminal operation, the KST3906TF can control current between its collector and emitter through a base-driven input. This makes it useful for switching loads, signal amplification, and biasing tasks where a small PNP transistor is required. Its compact package helps keep component placement neat while supporting automated assembly.

For engineers working on established designs, repairs, or replacement builds, matching the exact transistor type and package remains important. The KST3906TF provides a practical option when a 40 V, 200 mA PNP device fits the circuit requirements.
